Abstract
A wind turbine is disclosed. The wind turbine may comprise a tower having a top and a base, a generator located near the top of the tower, a main shaft operatively connected to the generator, a hub operatively connected to the main shaft, a plurality of blades extending from the hub, and at least one electrical conductor connected to the generator, the conductor configured to carry electric power from the generator to the base of the tower. The wind turbine may further comprise a conduit enclosing the conductor with the conduit having a lower air inlet opening and an upper air outlet opening. The conduit removes heat generated by the conductor by inducing a chimney effect, causing the heat of the conductor to rise up the conduit and out of the tower through the upper air outlet opening, while drawing in air from outside the tower through the lower air inlet opening.
